I am a 21 year old male, after intercourse last night with my girlfriend (20 years old), I pulled out as you do, went to remove the condom, this is when I noticed a white liquid on my pubes, I wiped it away and discarded of it. But now I'm worried in case it was in fact semen that got out of the condom and could somehow get my girlfriend pregnant? If it wasn't semen, what could is possibly be?

When women are sexually excited they get "wet". Sometimes that "wet" is a white type of liquid. Varies at times depending on time of the month too. Whena women discharges at ovulation, it can also be more of a white substance. If you were penetrating her to the point of your pubic hair, I'd just guess it was transfer from her.
